Crimson Stairs

Overview

Crimson Stairs is one of the 30 variants of this shape in the game. What changes between them is the material, and with it the hardness, the drops, the durability and the recipe — so every figure on this page is this variant's own. Oak Stairs is the same shape in a different material.

Crimson Stairs is a Nether block in Minecraft Java Edition 1.21.4. A crafting table turns its ingredients into Crimson Stairs. Its hardness of 2 makes it a normal, unhurried block to mine.

Mining it returns the block itself, so it is safe to relocate. A full stack holds 64. It is crafted from Crimson Planks.

Nothing on the crafting grid is made from it.

About the crimson set

Crimson is not wood at all — it is fungus, harvested from the huge crimson fungi that grow on nylium in the crimson forest — and that biology gives the whole set its defining property: crimson blocks are completely fireproof. They will not burn, fire will not spread across them, and lava will not set them alight, which makes crimson and warped the only sensible building materials anywhere near lava or in the Nether generally. The set covers planks, stairs, slabs, fences, gates, doors, trapdoors, signs, hanging signs, buttons and pressure plates, but there is no crimson boat, because a stem is not a log. Crimson stems strip with an axe like a log and the planks are a deep maroon-red found nowhere else. Bone meal on crimson nylium grows a new huge fungus instantly, so the set is fully renewable from one nylium block.

How long it takes to break

Crimson Stairs sits at hardness 2: 3 seconds per block with your fists, 0.35 with the correct netherite tool.

Iron takes 0.5 seconds against diamond's 0.4, so the upgrade worth making for this block is the one to iron.

The drop does not depend on the tool — bare hands work as well as anything — so the table below is purely about speed.

The Efficiency formula is level² + 1 added to tool speed — at V that is about 3.5 times the unenchanted rate.

Tool	No enchantment	Efficiency III	Efficiency V
Hand	3 s	3 s	3 s
Wooden	1.5 s	0.25 s	0.15 s
Stone	0.75 s	0.25 s	0.1 s
Iron	0.5 s	0.2 s	0.1 s
Diamond	0.4 s	0.2 s	0.1 s
Netherite	0.35 s	0.2 s	0.1 s
Golden	0.25 s	0.15 s	0.1 s

Properties

Crimson Stairs has a blast resistance of 3, so a nearby explosion will usually destroy it. It blocks light completely and emits no light of its own. Stack size is 64 — the standard full stack. The block is tagged for axes, and only that class gets the speed bonus; everything else mines at bare-hand rate.
